Today I want to discuss little games. Playing games also could be a mentally-stimulating brainstorm. Take bingo（a simple game by dividing into 25 grids, which are filled in different words or phrases） for example, there are many different ways to enhance the amusement. Every Tome, Dick and Harry only knows use Arabic numerals, but we can change numbers to another terms or a series of relating elements, such as singers, fruits, TV channels, nations, cities, stationeries, phrases, trademarks and so on. It’s very interesting by doing that. Rest assured that you can’t find adequate words, believe in the potential of your memory and the fitting words will come into your head in a minute. You can tell what I have mentioned are including many kinds of fields. Nations, cities for geography; phases for linguistic; singers, TV channels for entertainment; stationeries, fruits for common sense; trademarks for well-known brands. And all the things depend on how observation you put in the daily life. Besides that, what you fill in the grids may have something to do with personality. A trivia game also hide in complicated and funny thoughts.
